Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: I need a summary of this excerpt from NPR. Keep it under 50 words. 

Jerry Springer, a broadcaster, author, politician, journalist, actor, lawyer and host of a daytime show so outrageous he once apologized by saying it "ruined the culture," died today at age 79 in his suburban Chicago home after a brief illness, according to a statement from his family.

Though he had a lot of high-profile jobs over his lifetime – including mayor of Cincinnati – Springer was best known as host of The Jerry Springer Show, a syndicated TV program which lasted for 27 years, featuring provocatively sensational topics and confrontations among the guests, sometimes degenerating into fistfights.

Springer started his talk show in 1991 as a more conventional affair. Dressed in a suit and tie with glasses, he looked like a younger version of talk-TV titan Phil Donahue, and questioned guests while roaming the crowd with a wireless microphone in the same way.

But over time, Springer began to feature more outrageous guests and subjects, with cheating spouses, open racists, and button-pushing, explicit issues guaranteed to spark arguments.

The show's success became one of the pillars of the tabloid talk show movement which included hosts like Maury Povich, Sally Jessy Raphael, Jenny Jones, Montel Williams and Morton Downey Jr. Springer, a likable, charismatic guy with a conventional look and just-asking-questions manner, always came across as a more buttoned-down counterpoint to his outrageous guests.
Response: After a brief illness, Jerry Springer died at age 79. Despite being mayor of Cincinnati, Springer was best known for hosting The Jerry Springer Show. The show started in 1991 and involved controversial, outrageous guests and subjects, such as cheaters, racists, and issues guaranteed to begin arguments. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
